Heavy rain, gusty winds and thunder rolled through the Baltimore region Thursday night.

The National Weather Service called for thunderstorms with potentially damaging winds and a chance for tornadoes. Storms held out for most trick-or-treaters, beginning around 9 p.m. The weather was expected to last until at least midnight.


A tornado watch was in effect until midnight across Central Maryland — including Anne Arundel, Carroll, Baltimore, Harford and Howard counties.

A severe thunderstorm warning was issued for Baltimore, Harford, Prince George’s, Howard, Cecil and Montgomery counties through at least 11:30 p.m., according to Maryland Emergency Management Agency.

The Baltimore County Fire Department said in a tweet around 10:30 p.m. that it was responding to several incidents with vehicles stranded in floodwaters. The department reminded drivers to not drive through standing water. Firefighters had to rescue at least one person in Woodlawn who was standing on the roof of their car because it was stuck in floodwater.

The Howard County Fire Department also tweeted that it wa helping drivers with cars stuck in water around the Mall in Columbia.

The Bay Bridge was under full restrictions, the Maryland Transportation Authority said in a tweet. The restriction, which stops tractor-box trailers from going over the bridge, is only implemented when winds reach 50 mph or greater for at least 10 minutes. only automobiles, pickup trucks, flatbed trailers, commercial buses and heavy-laden tractor/trailers are permitted to cross the bridge.

“If you don’t have to be out tonight, don’t go out," meteorologist Ray Martin.

The weather hazards came as a “very strong” cold front moves across the eastern part of the country, meeting warmth and humidity that are unusual this time of year.

Temperatures dropped to just 60 degrees overnight Wednesday into early Thursday morning, which is close to normal highs for this time of year in Baltimore. Highs reached the mid-70s Thursday afternoon, more than 10 degrees above normal. The dew point, a measure of humidity, reached 70 degrees Thursday afternoon, a level typical for hot and muggy summer days. By 11 p.m., temperatures dipped back below 60.

On the other side of the approaching cold front, frigid air covers the western two-thirds of the country. Temperatures were in the 20s and 30s Thursday morning from Las Vegas to Chicago, where record-setting snow was reported.

That sharp contrast was expected to fuel severe weather from the Carolinas to Pennsylvania. Wind advisories were in effect in Western Maryland, and from North Carolina to Michigan to Maine, with gusts of up to 50 mph possible.

As rain continues, and with the effects of a new moon still present, a coastal flood watch is also in effect in the Baltimore region until early Friday morning.

Once the cold front passes, November is forecast to begin with a freeze for much of Central Maryland. Temperatures are forecast to peak in the mid-50s Friday, and then drop into the lower to mid-30s overnight Friday into Saturday. Similarly chilly and dry weather is forecast through the weekend and into early next week.
